Why will orders, that I know have been submitted, not download to lab?

If you know that you have submitted Orders, but Photogize Lab reports that you have "no new Orders", it is likely that you have mistakenly checked "Use Harvest Rules" in your Account Properties. You should check "Use Harvest Rules" if you have a multi-store workflow and you want to route orders. If "Use Harvest Rules" is checked, only orders which match the ship types, pickup types, and product types will get harvested.
